Has anyone else noticed that sometimes when you are working in one app, then switch to another to do some other work there for five or ten minutes, then when you switch back to the first app it then resets itself and goes back to its starting screen, losing what you were working on? Or it simply just refreshes itself slowly and unnecessarily but eventually does return you to where you were? The "Background App Refresh" setting has no effect on this since this issue isn't about what apps do in the background but rather what they do when they're brought back to the foreground. I have an iPad 2 and never saw this problem with iOS 6. I'm not positive but this problem may be limited to the iPad 2, since I believe it has less memory than the iPad 3 and later models (though I may be wrong). The iPad therefore can't handle the change in iOS 7 that I'm guessing was made in how the OS handles switching among apps. I'm not sure about my analysis, just trying to figure out what's happening. Glad to hear what experiences others are having.
